C # Language Basics (accompanying notes)

Write some of the notes that you remember, which is another notebook.

C#

Data Type
string is a reference type; Int,double is a value type;
string= string (not numeric/), int= Integer (not decimal) long= integer (larger than int); double (large value) ;
Type Conversions
( cast/implicit conversions); (there is no coercion between the reference value and the value);
casts are preceded by a variable (for example, int\double), and can only be applied to conversions between numeric values, preceded by a variable (type).
implicitly converts convert. to (Console.readine ());//convert. Todouble\tostring\toint32; Int.parse (Console.readine ());
operator
Arithmetic: +-*/% + +--; (++\ to add 1)
+ + (variable + +, Post + + first assignment, after operation; + + variable, first operation, then assignment);
Relationship:> < >= <= = = = (bool//compares a value to bool to receive this value) for judgment;
logic: (&&) with (and); ) or; (! Non.//priority in the top level of this table, only for the bracketed content followed by, and when and and or when it appears in a piece, the first count and (the operator priority);
Condition: (? :) If-otherwise;
Statement
Sequential statements:
branching statements: if else;if nested; swith (variable) case (Case1,case2,case3 ... ) (Swith is unable to do greater than);
Loop statement for; while, if (e.g.) {"I ate a stone" continue;} if (for example) {stop loop break;} (for starting from 0 less than, starting from 1 less than equals;)
Jump statement:
Exception statement: Try---catch---finally

This is easy to read, maybe some day in the future, you can see ——————————
